TO ALL WHOM IT MAY CONOERN:

Be it known that we, CONRAD WITT and ANDRUS SINA, of Davenport, in the county of Scott, and State of Iowa, have invented a new and improved Flax and Hemp-Brake; and we do hereby declare the following to be a. full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of our invention vconsists in three cylinder brake-rollers, so arranged that the brake-knives mesh into each other, and the said knives are only pla-ced about three-fourths inch apart on the circumference of the cylinders. The cylinders are propelled by gearing ruiming into each other. The hemp or ilux, in its raw state, is carried into the machine, and taken from the machine broken by means of a canvas apron run upon five rollers, propelled by helting running upon pulleys attached to the pinions of one of the cylinder brake'- rollcrs, and upon the largest roller. Underneath the cylinder brake-rollers are placed two cleaners, which consist of two fz1nsnith toot-hed edges secured to the pinions, which run rapidly and knock the shires from the fibre part ofthe flax or hemp as it passes through. There are sctscrews attached to the journals of the forward under cylinder brake-rollers for the purpose of letting the knives of the brake-rollers mesh into each other at a greater or less distance, as the case may require.

i Figure l isn-side view, showing the gearing, the., of ou1"invention.

Figure 2 is a section. l

Figure 3 is a plan looking down upon the machine.

Figure 4 is a section of slidojournalson each end of brakc-roller C'.

Similar letters of reference indicate corresponding parts in the four figures.

a, figs. 1 and 2, is the bottom of frame; b, figs. l and l3,-sides of frame; c e c, figs. 2 and 3, the cylinder brake-rollers; and'd, figs. 2 and 3, the knives upon said brake1'olleis, which are left apart so that shires will drop through said cylinder brake-rollers. e e.e 0 eH, fig. Q, rollers, upon which the canvas platform runs, andlfis the said canvas. The roller e is propelled by belting g, shown in iig. 1, running upon a pulley attached to pinion ot' cylinder of ineke-roller c. 7L, g. 1, is the gearing connecting brake-rollers together. z', 1, is the pulley or gearing to which is attached the power to propel the whole machine. jj', fig. 2, are the cleaners, propelled by belting f, shown in fig. l, running upon a pulley attached to pinion of brake-roller e. in fig. 4, is the slide journal ou cach end of cylinder brake-roller c'f m are the set-screws, for regulating the meshing together of the linivesin bral e-rollcrs c c e, shown in iig. 2. 1t are the set-screws for holding journals Zin a firm position. The canvas platform f to be extended to any desired length at both front und rear to suit the convenience of machine. Y

What we cla-im as our improvement, and desire to secure by Letters Patent, is-

The manner in which the flax or hemp is carried `into and taken from the machine by canvas plattorn f, running upon rollers e e c e em', iig.

We claim the form of the construction of the cylinder brake-rollers c c e with knives d, meshing into each other and as regulated by slide journal Z, fig. 4.

fe furthermore claim cleaners j'js'nown in fig. 2. Thus the above constitutes our claim as heretofore set forth. i

CONRAD WITT,

ANDRUS SINA.
